Using nginx as a proxy to gunicorn / openerp

Following the by now best practices with 6.1, I am switching my prod and demo configruation to gunicorn. 

However, it is also recommended to setup a front-end to your server in order to make if faster and more robust.

 

Installing nginx on Ubuntu is easy as :

 

sudo apt-get nginx

setting up the server to proxy the gunicorn/ openerp, requires to add a site configuration in nginx. Here is a minimal version (it works but it contains no safety nor optimisation) :

 

server {

  listen 80;

  server_name demo.xxxx.be;

  location / {

    proxy_pass http://localhost:8069;

  }

}

See nginx.org for more info !

OpenERP using multi-processors with gunicorn

Due to Python limitation (aka GIL), OpenERP is basically single processor powered !

Starting 6.1, OpenERP is a wsgi application. Provided you use a good wsgi container you can now
benefit from all capabilities of your hardware.

Basic stuff:

easy_install gunicorn
easy_install psutil

Update the gunicorn.conf.py (db host, etc)

gunicorn openerp:wsgi.core.application -c gunicorn.conf.py

gunicorn provided you the ability to manage your worker process making openerp more reliable.

Config info for optimization etc at gunicorn.org

Enjoy !
